12 Claims.. (Cl. 189-73) YThis invention relates to windowconstructions, particularly to window constructions for railwaycars,'buses, airplanes, `airships and the like, and has for its object asimple and` eiilcient means for L5 holding the window sash assembled inthe window frame without the use of 'screws and the like, and

` also this' means for holding the window sash in` characters designatecorresponding parts in ally the views.

Figures 8 and 9 are fragmentary lsectional views of parts seen in Figure6 showing the` interlock between the strip in the bottom of the channeloi the window frame and the demountable side of the channel. 4 ,e Idesignates a window frame and 2 the framing of the structure formedlwith a 'window opening 3 in which the window frame I is mounted. In

the form shown in Figure 1, the window isrprovidedY with an upper andlower' sash,l one of which, as the lower sash 4, is capable-of beingraised and lowered, and in the construction` vided with a depressedportion 8 extending lengthwise thereof andwith a shoulder 9 at the outeredge of the depression toward the demountable side 1. The body issecured to thevehicle structure in any suitable manner, as by screws I0extending through the bottom into the frame 2.

II is a member in the channel for coacting with the sash. In the formshown in Figures l, 2, 3 and 4in which the sash is slida'bly mounted,the member Il is a guide member for the sash 4, it being hereshown asprovided with a rib I2 extending into a groove formed in a non-metallicU-shaped lining I3 located in a channel in each edge of the sash 4L f I4is a resilient compression cushion orpad interposedpbetween the memberII and the bote tom of the channel member I` and cushioning the memberIl and serving to compensate for misallnements in the framing 2 of thewindow openv ing or in the sash or `any other misalinements, so that thesash raises and lowers uniformly under all conditions, the cushion orpad I4 extending the full length of the guide member `I Iv or mem#position, or transversely of the channel or sash,`

andas here shown, the' demountable side 'I is formed with anangulariiange I5 for entering the depressed portion ofthe bottom 6 underthe pad I4, and this iiangeis formed with spaced apart offsets orshoulders I8 for snapping into openings I1 in the depression in thebottom 6, when the demountable side 'l has reached its normal position,the demountable side 'I compressing against the edge of the pad I4,which projects is `not tightly clamped betweeirthe sides 5 and 1, i

but is capable of a sliding movement during raising andlowering of thesash, while compensating for misalinements. The padding exerts asubstantially uniform outward'pressure against the guide' member `5.

By reason of the interlocking shoulders I6 and openings II, thedemountable side 1 is readily placed in position without the use ofscrews and the like. It maybe demounted by inserting a pointed tool as ascrew-driver at'A between the outer edge of the demountable side l andthe bottom 6 and prying thereon until the shoulders I6 are lifted out ofthe openings I1.

The essential feature oi this invention is the construction by which thedemountable side of the channel may be rea'dily replaced and removed andheld in position without screws in combination with a resilient paddingfor cushioning the sash.

In Figures 5, 6 and 7, a window construction is shown in which the sashis stationary and entirely surrounded by a resilient compressiblecushion. Also, the sash is shown as a double one with two glass panesand 2i spaced apart with a sealed space between them. 23 is a sash trameusually of metal and the margins of the glass pane are mounted in arubber seat 24 located within the channel in the frame 23. 25 is aspacer between the glass'panes. 'I'he window frame, which is mounted inthe window opening, is substantially of the same general construction as.that shown in Figure 4 and comprises a body including a side 28 and abottom portion 21 and a demountable side 28. 29 is the U-shaped mountingmember, usually of rubber, enclosing the sash frame 23 and having beadsor lips at 30 and 3i pressing against 'the margins of the panes 20 and2| outside oi the joint between the glass panes and the sash frame 23,to seal the joints and serve as an additional precaution to opening thespace between the glass panes to the outer air.

32 is a cushion or pad, corresponding to the cushion I4 (Figures 2 and4), this extending entirely circumferentially around the frame 23. 33 isan additional cushion of sponge rubber located to cushion the sashagainst lateral shocks. It is shown as interposed between one side ofthe frame 23 and thecontiguous side of the member or mounting 29. Thedemountable side 23 is practically the same construction as that shownin Figure 4, it having an angular flange 34, corresponding to theangular flange I5 (Figure 4). The offsets or shoulders 35, correspondingto the offsets or shoulders I6 (Figures 3 and 4) snap into openings 31in a strip 38 instead of in openings in the bottom 21 of the body of thewindow frame 28. The shoulders 35 interlock with the openings 31 in thestrip 38, when the demountable side 28 is pressed into nornal oroperative position.

In the form shown in Figure 6, the demountable side 29 does not compressagainst the cushion 32 but compresses against one side of the member ormounting 29, which in turn presses against the resilient compressiblecushion 33. The bottom of the window frame is secured to the carframingas in Figure 1, as by screws 40, and usually a heat insulatingstrip 4I overlies the bottom oi the channel of the window frame. 'I'hisis heldin position by the strip 38 overlying the insulated strip 4I andsecured to the bottom of the channel of the window frame, as by rivets43. The demountable side 28 is usually -formed in sections which abutagainst each other at (Figure 5). The two side sections 289 are placedin position, after the top and bottom sections are mounted in position,and also in demounting, the sections 28, are rst demound.

In Figure '1, the pad, corresponding to the pad I4, is shown as acorrugation 48 formed in the bottom of the U-shaped mounting 29 and thedemountable side 49, corresponding to the side 1 or 28 (Figures 2 and 6)is formed with an outwardly extending angular ange 53, which enters intoan outward extension 5I of the bottom 52 of the channel of the windowframe. 'I'he extension 5| is provided with an angularlyextendingshoulder 53 against which the edge of the ange 50 abuts at 54when in normal position, and the'ilange 53 is formed with notches 55 atintervals for the insertion of a pointed tool for use in demountlng theside 49. Also, one of the beads 3| of the U-shaped member or mounting 29is formed with a shoulder at 56 against which the upper edge of thedemountable side 49 abuts, when in normal position.

In any form of the invention, the demountable side is moved into normalposition by a bodily movement and snaps into interlocking engagementwith the bottom of the channel of the body of the frame member of thewindow frame by a bodily movement transversely of the window frame orsash and cushions against the cushioning means for the sash.
